How a single blood sample could predict your lifespan, study finds
Researchers have developed a method to assess ‘ intrinsic capacity ’, a measure of mental and physical function crucial for healthy aging , using just a single drop of blood or saliva. The new test that looks at DNA methylation could help predict a person’s overall risk of death and even track how they’re aging.
Defined by the WHO, intrinsic capacity refers to “all the physical and mental capacities that a person can draw on and includes their ability to walk, think, see, hear, and remember.” It is the sum of a person’s mental and physical capacities.
According to TheMedicalNewsToday, the innovative discovery could play a big role in helping people live healthier and longer lives through more personalized care. It offers a more accessible way to support healthy aging, making it easier and more accessible than traditional methods.
Blood and saliva samples shed light on cellular aging
From blood and saliva tests, the researchers collected data on DNA methylation- a process that activates or deactivates genes. Due to developmental mutations, environmental factors, and abnormal methylation patterns, DNA methylation changes over time.
They used this information and data to construct an epigenetic predictor of intrinsic capacity (IC), then evaluated associations between IC clock and mortality.
Tracking aging and predicting risks
The discovery of this blood test signifies a shift towards personalized healthcare , where interventions are tailored based on an individual’s biological age. By identifying the early signs of aging, healthcare professionals can implement preventive measures to delay the onset of age-related diseases , enhancing quality of life and lifespan.
Researchers have suggested several measures to help ensure healthy aging:

Researchers have suggested several measures to help ensure healthy aging:
- Focus on eating a healthy diet (like MIND or Mediterranean) with fruits, veggies, whole grains, and healthy fats.
- Stay physically active with exercises like aerobics, strength training, and balance exercises.
- Keep your brain occupied with cognitive activities.
- Manage chronic diseases and stress
- Maintain social connections and networks
